Nah. I’m interested in quickly querying on-disk data specifically, ie proto-based application logs and the like (another thing the world needs to adopt more broadly imo).
Of note, Prototool has a binary-to-json command, so assuming your Protobuf files are in path/to/proto/files, and you had a newline-separated log file of Protobuf messages foo.bar.Baz, you could do:
cat /path/to/log.file | prototool binary-to-json path/to/proto/files foo.bar.Baz - | jq .search.term
